Which LCD or DLP Projector Should I Buy or Rent?
When Renting or buying an DLP or LCD Multimedia Projector you need to match the brightness of the projector to your audience and room size as well as consider your projector video.
(PRWEB) January 5, 2005 -- Larger rooms and audiences require higher bulb
strength brightness. Projector bulb strength brightness is measured in ANSI
lumens or lumens. You also need to take into account the primary use of the
projector, full motion video vs. static data.
Projectors range from
around 650 to 5000 lumens in brightness. Presentations where the lights are on
are the most desirable, because you can interact and demonstrate off-screen with
your audience.
Another consideration is portability of the projector.
Lower lumen units are the most portable. As a general rule, as you increase bulb
strength brightness, you reduce portability. High lumen projectors are larger
and weigh more than low lumen projectors.
Less than 1000 lumens -good
for low ambient light, presentations.
1000 -2000 lumens -These are the most
popular units being sold and rented today. Very practical and will work with
some ambient light.
3000 lumens -Much Larger unit than the1000 to 2000 lumen
units. Good for audiences of less than a hundred with ambient light.
5000 lumens - For audiences of 100 or more under brighter lights
6000+ lumens - For large events like conventions, conferences and tradeshows
where thousands of people need to view a presentation at the same time.
LCD Projectors vs DLP Projectors
LCD stands for Liquid Crystal
Display and DLP stands for Digital Light Processing. LCD is an analog-based
display technology employing 3 fixed panels of pixels (one panel each for the
RED, GREEN, & BLUE components of an NTSC video image).
LCD also
delivers a somewhat sharper image than DLP at any given resolution.
LCD
projectors work better for static Microsoft PowerPoint® presentations or
detailed financial spreadsheets. DLP works better for full motion
video.
LCD projectors usually produce significantly higher ANSI lumen
outputs than do DLP projectors with the same wattage lamp.
DLP projectors
have a much higher pixel “fill factor” than LCD. DLP-based projectors generally
produce a much smoother looking image compared to LCD-based projectors of
similar resolution.
DLP-based projectors have a high contrast ratio and
efficient use of light. Contrast ratio is figure of merit that compares the
ratio between the brightest white and the darkest black that a projector can
produce. Generally, a better contrast ratio leads to better black levels and,
therefore, a more realistic presentation of darker scenes in movies and TV
programs.
DLP projectors consists of a single chip rather than three in
LCD projectors. DLP projectors tend to be more compact because they have fewer
components.
All of the current 3-pound portable projectors on the market
are DLP projectors. Most LCD projectors are five pounds and up. The higher lumen
models are significantly heavier and larger. High lumen projectors are not
considered portable.
Should I buy or rent a projector?
LCD and DLP
projectors are available for rent or purchase from Rentacomputer.com.
So
should you buy or rent? That depends on how often and where you need the
projector. If your presentation is in another town, lugging a projector thru
airports can be a high risk hassle. You can easily damage a projector by
dropping it out of a luggage compartment. Never check a projector thru baggage
at airports either. Baggage handlers will treat your expensive projector like a
suitcase.
If you are planning on using a projector at a fixed location
over a long period of time, then purchasing a new projector is a good idea.
Never buy a used or refurbished projector unless it comes with a new bulb. Bulbs
are very expensive. Projector bulbs cost between $200 to $500 for the more
portable units. They cost up to $2000 for the higher end projector
units.
